Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a breathing machine humidifier 2 is with preventing flowing backward structure, including breathing machine body 1 and can dismantle the humidifier 2 of being connected with breathing machine body 1. The humidifier 2 is detachably and fixedly connected with a sealing cover 23, and the sealing cover 23 is provided with an air outlet pipe 231 for communicating the mask of the breathing machine with the water tank 21. The end of the water tank 21 far away from the bottom is fixedly connected with a sealing ring 213, and the sealing cover 23 is detachably connected with the sealing ring 213 in a sealing manner. The sealing ring 213 is fixed to the water tank 21 by ultrasonic welding, and improves the sealing performance of the water tank 21 when the sealing cover 23 on the humidifier 2 is closed.

Referring to fig. 2, a water tank 21 with an opening on one side is detachably fixed in the humidifier 2, and the water tank 21 is communicated with an air duct in the respirator body 1 through the humidifier 2. An anti-reflux pipe 211 communicated with the air duct is fixedly connected to the inner side wall of the water tank 21, and a heating device 22 is arranged at the bottom of the water tank 21.

Wherein, the heating device 22 comprises a heat conducting plate 221 and a heating plate 222 arranged in the humidifier 2, the heat conducting plate 221 is fixedly connected to the bottom of the water tank 21, and when the water tank 21 is inserted and fixed in the humidifier 2, the heat conducting plate 221 and the heating plate 222 are mutually attached. The heating plate 222 generates heat after being electrified, and the heat is conducted on the heat conducting plate 221 to raise the temperature of the heat conducting plate, so that the sterile water in the water tank 21 can be heated conveniently, and the sterile water can rapidly generate humidified airflow to be mixed with air generated by the respirator.

In the present embodiment, the heat conductive plate 221 is made of a stainless steel material, and the water tank 21 is made of a copolycarbonate material. The stainless steel material not only has good thermal conductivity, but also makes the heat conducting plate 221 not easy to rust, thereby improving the service life of the heat conducting plate 221. The water tank 21 is made of a copolycarbonate material, which is distinguished from any other engineering thermoplastic by virtue of its unique combination of high heat resistance, toughness, clarity, light stability, and flow properties. Particularly noteworthy is its excellent heat resistance, so that the heat resistant temperature of the water tank 21 can be even as high as 260 ℃. Therefore, it is an ideal material for molded articles used under high thermal stress environments.

Referring to fig. 3, wherein prevent that the counterflow pipe 211 is oblate setting, oblate prevents that the counterflow pipe 211 improves its self structural strength to a certain extent to for circular prevent that the counterflow pipe 211 makes can contain more volumetric sterile water in the water tank 21, reduced the number of times of adding sterile water in toward the water tank 21, labour saving and time saving has improved work efficiency.

The anti-backflow pipe 211 is obliquely arranged at the cut of one end far away from the inner side of the water tank 21, so that the anti-backflow effect of the water tank 21 is further improved. Further, the air inlet of the air outlet pipe 231 close to the water tank 21 is arranged above one end of the inner side wall of the backflow preventing pipe 211 far away from the water tank 21, and the length of one side of the backflow preventing pipe 211 close to the air inlet of the water tank 21 is larger than that of one side close to the bottom of the water tank 21.

On the one hand, the gas generated by the respirator enters the water tank 21 after passing through the ventilation pipeline and the anti-reflux pipe 211, and due to the fact that one end of the anti-reflux pipe 211 is provided with a downward-inclined cut, the gas is enabled to diffuse downwards when flowing out of the anti-reflux pipe 211 and is fully mixed with the humidified airflow generated by heating of the sterile water to enter the air outlet pipe 231 and be sent to the lung of the patient, the wettability of the gas is increased, the patient is enabled to keep the alveolus moist, the activity of the patient is enhanced, and gas exchange is promoted. On the other hand, the humidifying air flow generated after the heating of the sterile water is upwards diffused, and can be accumulated on the sealing plate to generate water drops under the action of a long time, and the water drops drop in the water tank 21 under the action of gravity, so that the water drops are prevented from entering the anti-backflow pipe 211, and the anti-backflow performance of the breathing machine humidifier 2 is further improved.

Referring to fig. 4, a tapered ring body 212 is disposed inside the backflow prevention pipe 211, one end of the tapered ring body 212 is fixedly connected to the inner wall of the backflow prevention pipe 211, and the other end extends towards the end of the backflow prevention pipe 211 away from the inner wall of the water tank 21. The humidifying air current that produces after the aseptic water heating upwards diffuses and gathers in preventing against current pipe 211, forms the drop of water in preventing against current pipe 211 after long-time, because the setting of toper ring body 212 for in the drop of water is difficult for getting into vent pipe, and do not influence the gas admission water tank 21 that breathing machine body 1 produced, further promoted the anti-reflux performance of humidifier 2.

The implementation principle of the embodiment is as follows: before the respirator is used, a proper amount of sterile water is added into the water tank 21, then the sealing cover 23 is closed, and the temperature of the sterile water is increased by adjusting the heating device 22 to generate a humidified airflow. The gas generated by the respirator body 1 enters the water tank 21 through the ventilation pipeline and is mixed with the humidified gas flow, and the humidified gas enters the breathing mask of the patient through the gas outlet pipe 231 for the patient to use. When the breathing machine and the humidifier 2 move, as one end of the anti-reflux pipe 211 extends into the water tank 21, the sterile water in the water tank 21 is difficult to enter the ventilation pipeline, thereby avoiding the backflow phenomenon of the humidifier 2 and prolonging the service life of the breathing machine.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
